wxpython - 一个框架，多个面板，模块化代码

Question

我正在研究一个相当大的GUI项目，因此使用wxpython来构建它。我有一个框架，多个框架与他们自己的功能和一个主要文件，导入gui组件以及其他外部功能。我决定保持gui/wxpython代码不同以更好地模块化代码。

我的主要问题是如何执行单独的面板中的功能，以及如何使他们从我的主要python文件工作。

下面是我的wxPython代码示例：

import wx 

class MainFrame (wx.Frame): 

    def __init__(self, parent): 
     wx.Frame.__init__ (self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size(800,600), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL) 

     self.SetSizeHintsSz(wx.DefaultSize, wx.DefaultSize) 

     bSizer1 = wx.BoxSizer(wx.VERTICAL) 

     self.SetSizer(bSizer1) 
     self.Layout() 

     self.panelOne = panel_one(self) 
     self.panelTwo = panel_two(self) 

     self.panelTwo.Hide() 


     self.Centre(wx.BOTH) 

    def __del__(self): 
     pass 


class panel_one (wx.Panel): 

    def __init__(self, parent): 
     wx.Panel.__init__ (self, parent, id = wx.ID_ANY, pos = wx.DefaultPosition, size = wx.Size(800,600), style = wx.TAB_TRAVERSAL) 

     bSizer5 = wx.BoxSizer(wx.VERTICAL) 

     self.m_button2 = wx.Button(self, wx.ID_ANY, u"MyButton", wx.DefaultPosition, wx.DefaultSize, 0) 
     bSizer5.Add(self.m_button2, 0, wx.ALL, 5) 

     self.SetSizer(bSizer5) 
     self.Layout() 

     # Connect Events 
     self.m_button2.Bind(wx.EVT_BUTTON, self.changeIntroPanel) 

    def __del__(self): 
     pass 


    # Virtual event handlers, overide them in your derived class 
    def changeIntroPanel(self, event): 
     event.Skip() 



class panel_two (wx.Panel): 


    def __init__(self, parent): 
     wx.Panel.__init__ (self, parent, id = wx.ID_ANY, pos = wx.DefaultPosition, size = wx.Size(800,600), style = wx.TAB_TRAVERSAL) 

    ... some code in here ... 

    def __del__(self): 
    pass 

因此，这些都是我的GUI组件。然后，在我的主文件，我导入并运行GUI：

import gui 

class MainApp(gui.MainFrame): 
    def __init__(self, parent): 
     gui.MainFrame.__init__(self, parent) 

     self.panelOne = Panel1(self) 
     self.panelTwo = Panel2(self) 
     self.panelTwo.Hide() 

class Panel1(gui.panel_one): 
    def __init__(self, parent): 
     gui.panel_one.__init__(self, parent) 

    def changeIntroPanel(self, event): 
      if self.panelOne.IsShown(): 
       self.SetTitle("Panel Two Showing") 
       self.PanelOne.Hide() 
       self.PanelTwo.Show() 
      else: 
       self.SetTitle("Panel One Showing") 
       self.PanelOne.Show() 
       self.PanelTwo.Hide() 
      self.Layout() 


class Panel2(gui.panel_two): 
    def __init__(self, parent): 
     gui.panel_two.__init__(self, parent) 

def main(): 
    app = wx.App() 
    window = MainApp(None) 
    window.Show(True) 
    app.MainLoop() 

if __name__ == '__main__': 
    main() 

可以这样说，这个想法是，我要尽我所有的实现在我的主文件。我将如何去定义我首先在panel_one中定义的changeIntroPanel函数的功能？目前，这个想法是隐藏panelOne并显示panelTwo。

我以前做过类似的事情，但只有一帧。在这种情况下，因为所有的函数都是在MainFrame类中开始的，所以它是微不足道的。在这种情况下，我发布的代码将完美工作。

任何帮助表示赞赏。谢谢。

def OnInit(self, parent):用于wx.App，您需要使用def _ _init_ _(self, parent)。

关于__init__请检查：Using inheritance in python
